The Samsung DDR5 Memory Modules
Samsung is a global leader in semiconductor technology, recognized for its innovation and reliability. The M321R8GA0EB0-CWM DDR5 64GB module reflects Samsung’s commitment to delivering high-quality memory solutions tailored for enterprise and hyperscale computing environments. Choosing Samsung memory guarantees consistency, rigorous testing standards, and long-term reliability in demanding scenarios.
Capacity: 64GB
With a single M321R8GA0EB0-CWM 64GB module, this DDR5 RDIMM provides ample capacity for memory-intensive tasks such as virtualization, in-memory databases, AI inference, and large-scale application hosting. The high density allows system architects to scale memory footprints efficiently while minimizing the number of physical modules required.
PC5-44800: The Bandwidth Benchmark"PC5-44800" M321R8GA0EB0-CWM is the industry's standardized designation for DDR5-5600 modules. The "PC5" prefix identifies it as DDR5, while the "44800" refers to the peak transfer rate in megabytes per second (MB/s) per module. Calculated as (5600 million transfers/second * 8 bytes/transfer), this yields a theoretical peak bandwidth of 44.8 GB/s for a single module. In multi-channel server platforms (commonly 8-channel), aggregate system bandwidth can exceed 350 GB/s, dramatically accelerating data-intensive applications.
Registered DIMMs (RDIMMs) Enabling Higher Capacity
An RDIMM incorporates a register (or buffer) on the module for the command and address signals. This buffer reduces the electrical load on the server's memory controller, allowing it to support a greater number of memory modules per channel. This is essential for populating servers with large total memory capacities—think 1TB, 2TB, or more—which is a common requirement for in-memory databases (like SAP HANA), large-scale virtualization, and big data analytics platforms.
RDIMM vs. UDIMM and LRDIMM
Used in desktops and entry-level servers. Offers slightly lower latency but places a direct electrical load on the memory controller, severely limiting the number of modules that can be installed. Not suitable for high-capacity server configurations.
Firmware
As a first-party vendor, Samsung provides direct technical support for its memory components and works closely with major server OEMs (Dell, HPE, Lenovo, Super micro) to ensure seamless integration and timely firmware updates if required. Samsung server memory undergoes exhaustive testing procedures beyond standard industry qualifications. This includes extended temperature cycle testing, high-voltage stress testing, and compatibility testing across a wide range of server platforms. This results in modules built to endure the harsh, 24/7 operational environment of data centers.
Reliable ECC Registered Architecture
Reliability is a cornerstone of server memory design, and this Samsung M321R8GA0EB0-CWM DDR5 RDIMM excels in that area. It incorporates Error-Correcting Code (ECC) technology to automatically detect and correct single-bit memory errors. This helps prevent data corruption, system crashes, and unexpected downtime in enterprise environments.
Reliability
With ECC technology, the module detects and corrects memory errors on the fly, preventing data corruption and safeguarding mission-critical applications. This reliability makes it a preferred choice for enterprise servers that demand continuous uptime. Samsung, a leading global memory innovator, the M321R8GA0EB0-CWM module delivers optimized reliability, performance, and energy efficiency. This model is engineered to fit seamlessly into modern server infrastructures requiring scalable memory capacity.
Compatibility
This server memory is designed for compatibility with a wide range of enterprise-class systems, including those from industry leaders such as Dell, HPE, Lenovo, Cisco, and Super micro. Its registered design ensures that it integrates seamlessly with modern server motherboards supporting DDR5 architecture. The 288-pin configuration also ensures straightforward installation, reducing downtime when upgrading or expanding server infrastructure. The Samsung M321R8GA0EB0-CWM memory module is intended for use in compatible DDR5 server platforms that support registered ECC memory. It integrates seamlessly with enterprise-grade systems from leading server manufacturers, making it a reliable upgrade or replacement option for IT professionals.
